Abstract
A tire for a civil engineering vehicle the endurance of which has been improved by the addition of an anti-creep layer () with a thickness E2 interposed between the airtight inner layer (), with a thickness E1, and the reinforcer coating layer () of the carcass reinforcement (), with a thickness E3. The thicknesses E1, E2 and E3, being measured in millimetres in a shoulder region forming the transition between the crown and each sidewall of the tire, satisfy the following equations: 2≤E1≤4; 6≤E2+E3 and E1/E2≥0.6. In addition, the viscoelastic loss P60 of the elastomeric mixture M2 of the anti-creep layer () is at most equal to 20%.
